Claims. (CL 2li-205.11)

The present invention relates to slide fastener constructions and aimsgenerally to improve constructions of slide fasteners andthe like.

- One of the objects of the invention is the provision of an improvedterminal end for coil type slide fasteners in which the end provides ananchor for the coil end.

A further object of the invention is the prol vision of an improvedseparable end `stop for portion of a slide fastener showing the endstops connected;

Fig. 5 is a transverse sectional view of the female end stop as taken onthe line l-l of Fis. 4:

Fig. 6 is an enlarged perspective view ofthe disassembled parts of thefemale end stop according to the illustrated embodiment of theinvention;

Fig. 'I is a front elevation of the male 'terminal end; and

Pig. 8 is a vertical central sectional view of the male terminal stop. i

Referring to the drawings, the improved slide fastener constructioncomprises a pair of opposed stringers or tapes l, I0 to the meetingedges of which are secured the fastener elements. herein shown asconsisting of helical coils II-II of non-circular ribbons adapted tointerlock in meshing engagement when the fastener is closed by means of'a slider, not shown.

The stringere or tapes l and I0A are preferably woven or otherwiseconstructed to a flanged cross section, preferably T-shaped, to providelateral anges ll--III onone or both sides of the web lll-IIIb of thestringers I and Il. respectively. Thev coils are suitably secured to the2 as for examplel by weaving the tapes to the successive convolutions ofthe coils as disclosed in my copending application `Serial No. 579,746,died February 26, 1945 now matured into Patent Number 2,504,078 datedApril 1l, 1950.

According to the invention, means areV provided to secure the terminalends of the coils to the stringer so as to hold the coil securely inplace relative to the Stringer edge to relieve strain on the threadsattaching the-successive coil convolutions to the stringer tapes Suchmeans may be embodied in a separable end stop for the fastener,permitting the fastener to be separated as desired after the slider hasbeen moved to' the bottom of the fastener, as is the case where thefastener is used as a closure for garments, such as coats,Jackets,.sweaters and the like. In the embodiment selected forillustration in the drawings, the invention may be embodied in male andfemale members I l and It. respectively, for this purpose. i -1 The malemember or terminal end Il for the stringers` preferably comprises anelongated sleeve having a relatively at body portion l1,

lan integral end portion Il and inturned side nanges il spaced from andparellel to therbody il (see Figs. 7 and 8). The body I1 is preferablyof a width 'to overlie the two iianges l* or Il* of a stringer and theend portion II preferably abuts the end of the Stringer. `The member ilis securely attached to the Stringer by crimping the inturned flangesvI9 against the opposite face of the stringer flanges te-ll, thusencompassing the end of the stringer flanges on all sides.

Preferably the end IIL-l2* of the coils H--ll are extended into the endstops and gripped between the body I1 and flanges I9. or as illustratedin Figs. 'I and 8, the end I2* of the coil may be formed as an eye orloop to receive a lug il on the upper edge of the front wall I1 of themale member I5 and thus anchor the end of the coil to the member I5.Thus the members Il provide an anchoring socket for the terminal ends ofthe coils serving to relieve strain on the threads attaching thesuccessive coil convolutions to the stringer flanges.

In the illustrated embodiment of the invention the male member may be,and preferably is constructed as above described, and as illustrated inFigs. '1 and 8.

-The female member It which may form a bottom stop may be and preferablyis similarly formed with a body 20 and inturned flanges 2| to embraceopposite sides and edges of the faceoftheiiangeslandlibymltablemeam. ssltringertowhichltisattachedaswellasthe terminal end of the coil, auch esthe coil end il* as shown in Figs. 5 and E. The female member iB isfurther formed with a socket or cup 24 formed integrally with orattached to the stop IS to receive the male member iii, and is of suchdimensions that it forms a stop for the slider as will be understood.

As herein disclosed the female member l@ may be formed at its terminalend with oppositely disposed laterally extending ilanges 2 and 23projecting respectively from the body and the ilange 2| as illustratedin Figs. 4 and 6, adapted to be embraced by the cup or socket member 24whereby the latter may be securely attached to the member it.

The cup or socket 21! may be suitably formed to receive and be attachedto the member i5 while providing a laterally projecting recess for thereception of the male member l5. One desirable construction of cup orreceptacle 2d is illustrated in the drawings, and comprises a memberhaving an intermediate base portion 25 and angularly disposed opposedchanneled sides, the latter having a web portion 2l and inturned edgeflanges 28. Such a cup or receptacle may be simply and economicallyformed :from a channel shaped strip, the flanges or which are cut froman intermediate portion throughout a length slightly greater than thewidth oi the body it and ange 211. The cup 2Q may be folded as shown inFig. 5 and then slipped over the terminal end of the stop i6 so that thebase 2li oi the cup 2d underlies one oi the flanges 22-93 and theinturned flanges 2B overlie at least one oi the ilanges 22 and 23. Asillustrated, the base 2@ oi the cup 2d underlies the flange 22 or" thestop l5 and the ilanges 28 of the cup overlie the iiange 23 of the stopIS. Thus the socket or cup 24 is securely attached and locked to thestop body l5 and is prevented from longitudinal displacement thereon.

The width of the flanges 22-23 oi the female end stop I6 is such as tomaintain the adjacent edges of the ilanges 28 of the sides 2l. inspacedapart relation to provide guides 29 for the passage of theStringer Webs 9b and llb as is illustrated in Fig. 3, thus avoiding thenecessity of extending the end stop l5 and i5 below the end of itsStringer ill.

The members I5 and it will ordinarily he securely attached to thestringers against displacement therefrom by clamping action of thecompressed or clinched body and opposed edge flanges I'l--IS and 2li-2l.Ii desired, additional locking means may be provided in the form oi atongue 3U cut from the metal oi the end stop, for example, the body ilor 2c, and pressed inwardly into biting engagement with the associatedStringer.

Advantages of the invention reside in the simplicity of construction aswell as of application of the component parts of the separable end stopto the Stringer. The provision of a terminal'end member having a bodyand spaced opposed flanges permits the members to be readily applied toa coil-attached Stringer with the Ybody overlying one face of theStringer and terminal end of the coil and the edge ilanges I9 and 2|bearing against an opposite face of the Stringer, so that compression ofthe body and anges together securely binds the Stringer end and coil endtogether. Furthermore, the provision of a socket or cup 24 of the typeillustrated and described on the female end stop permits the readyinterlocking of the adjacent Stringer ends.

Although I have illustrated and described a. single preferred embodimentor the invention, I do not intend to be limited thereto as the scope ofthe invention is best defined in the appended claims.
